  1. An ideal liquid refrigerant should

  2. A.
    not have a subatmospheric vapour pressure at the temperature in the refrigerator coils.
    B.
    not have unduly high vapour pressure at the condenser temperature.
    C.
    both (a) and (b).
    D.
    have low specific heat.

  3. If the heat of solution of an ideal gas in a liquid is negative, then its solubility at a given partial pressure varies with the temperature as

  4. A.
    solubility increases as temperature increases.
    B.
    solubility increases as temperature decreases.
    C.
    solubility is independent of temperature.
    D.
    solubility increases or decreases with temperature depending on the Gibbs free energy change of solution.
